Benefits of technology

The present invention allows for the efficient analysis of workers' postures to detect if they are in the correct position for their job. This is done by comparing the worker's joint positions to a predetermined reference body posture that represents the starting or finishing of their work. This approach reduces the burden on the administrator and ensures that analysis is performed efficiently for multiple workers.

Problems solved by technology

However, since different workers hold such an object in different ways, the prior art technology cannot make analysis with high precision without performing a setting operation for each worker to set a corresponding image pattern(s) and a corresponding portion(s) of an image where the object appears.
This has caused a problem that, when an increased number of workers become analysis targets, there would be an undue burden on an administrator to perform the setting operations for the analysis.

Embodiment Construction

)

[0026]A first aspect of the present invention made to achieve the above-described object is a work analyzing device in which a processor is caused to perform operations to output analytical information on a work efficiency status of a worker based on video recordings of working activities of the worker, wherein the processor is configured to: perform a joint position estimation based on the video recordings to estimate joint positions of the worker; perform a posture match determination based on results of the joint position estimation to determine whether or not to achieve a posture match between a posture of the worker and a predetermined reference body posture; and generate, based on results of the posture match determination, the analytical information on the work efficiency status of the worker.

[0027]In this configuration, operations are performed to detect a match between a posture of a worker and a predetermined reference body posture based on joint positions of the worker, ...

Abstract

In order to enable, even when an increased number of workers become analysis targets, efficient analysis on work efficiency statuses of workers without putting a greater burden on an administrator to perform setting operations for the analysis, analytical information is produced by performing a joint position estimation based on respective frames of video recordings to estimate joint positions of a worker, performing a posture match determination based on results of the joint position estimation to determine whether or not to achieve a posture match between a posture of the worker in each frame of the video recordings and a predetermined reference body posture, and measuring, based on results of the posture match determination, a working time and a presence time of the worker used as analytical information on a work efficiency status of the worker.

Description

TECHNICAL FIELD[0001]The present invention relates to a work analyzing device and a work analyzing method in which a processor is caused to perform operations to output analytical information on a work efficiency status of a worker based on video recordings of working activities of the worker.BACKGROUND ART[0002]In factories, operation efficiency can be improved by analyzing work efficiency statuses of workers and changing operating procedures or other ways of work based on results of the analysis. For this reason, there is a need for technologies for analyzing work efficiency statuses of workers in an efficient manner.[0003]Known such technologies for analyzing work efficiency statuses of workers include a method which involves: capturing video recordings of working activities of a worker; extracting, from the video recordings, images including a predetermined image pattern in a predetermined portion of the image; determining a time when each extracted image is captured as start / en...
